Question

Simple Harmonic Motion: A mass of 0.4 kg, hanging from a spring (k= 80N/m) is set into an up-and-down SHM. What is the speed of the mass when moving through the equilibrium point? The starting displacement, A, is 0.10 m.

Answer 1

I'm not sure how to get the answer without knowing time.

Answer 2

How did you proceed?

Answer 3

I calculated acceleration, which was 20 m/s, and the gratitational force on the box, but I don't think either of those help.

Answer 4

I honestly have no idea how to solve this question. My teacher basically just gave us a bunch of equations and told us to figure a bunch of questions out.

Answer 5

@theEric

Answer 6

Acceleration at what time?

Answer 7

At the equlibrium point.

Answer 8

Do you know what to do?

Answer 9

nm i solved it myself.

Answer 10

Nevermind! :)
